Why do browsers sometimes drain a lot of RAM until rebooted?

Answer 1

Some browsers treat each tab as a separate process. Each as it’s own program so to speak. So each gets its own little slice of RAM and it adds up. And sometimes the browser doesn’t give the RAM back even after closing some tabs. Rebooting clears out the memory.
